Surgical Oncology Open Access

Cancer is gradually becoming the leading disease-related cause of death of the human population. Thus, there is an ultimate need for innovation in drug discovery and development, especially in the area of oncology. Unfortunately, clinical attrition rates are a critical issue in drug development, particularly in oncology where over fourfold higher rates of attrition were determined in respect to other indications . Although, this trend presumably relates to the substantial heterogeneity and the inherent biological complexity of cancer, in order to track the source of this failure it should be interesting to chart the drug targets that researchers have traditionally focused on. It could be then realized that one of the fundamental issues that drove to this decline in pharmaceutical research and development is the philosophy that shaped the drug discovery process. The “one-gene-one-disease” theory sculpted the drug design concept to treat diseases by targeting individual chemoreceptors with a “magic-bullet” therapy. Drugs were thus traditionally rationally designed and tailored to target rigid protein binding pockets on the basis of complementarity, the so-called “lock-and-key” mechanism. This unidimensional approach on proteins presenting compact and well-ordered 3D architectures lead presently to the majority of ‘druggable’ targets: G-protein-coupled receptors (GPCRs) and enzymes. An open access publication is the one in which A complete version of the work and all supplemental materials, including a copy of the permission as stated above, in a suitable standard electronic format is deposited immediately upon initial publication in at least one online repository that is supported by an academic institution, scholarly society, government agency, or other well-established organization that seeks to enable Open Access, unrestricted distribution, interoperability, and long-term archiving.
